塑性开裂 meaning in English
plastic cracking
Examples
- The borderline w / b ratio for fly ash and silica fume concrete is about 0 . 36 and 0 . 4 , respectively . 5 ) polypropylene fiber can make them quite effective in the suppression and stabilization of microcracks in fresh concrete matrix
7 )在室外太阳辐射、 8m / s风速条件下,新拌混凝土的塑性开裂与水灰比有关,水灰比界限约为0 . 4 。 - From the experiments , we can see the affect of concrete performances mixing with liter polypropylene fiber and glass fiber is minor . compare with common concrete , the crack - load of concrete slab mixing with liter polypropylene fiber and glass fiber is marked improved . mixing with liter polypropylene fiber and glass fiber , the behavior of cracks - resisting of is marked improved , and the cracks are controlled and smeller
研究表明,在混凝土中掺入低掺量的聚丙烯纤维或玻璃纤维对抗压强度及抗拉强度的影响较小;纤维混凝土板比普通混凝土板的开裂荷载有较为显著的提高;加入低掺量的聚丙烯纤维后,混凝土板的抗塑性开裂性能有显著提高,可以抑制、细化裂缝。 - In the paper the effects of the made parameters , the main materials and environmental conditions on plastic shrinkage cracking were investigated . it can be concluded as following : 1 ) there was a critical w / c ratio of maximum plastic shrinkage cracking between lower and higher w / c ratio of concrete mixtures made with the same cement content per cubic meter , concretes with lower or higher w / c ratio being less prone to plastic shrinkage cracking and the w / c critical ratio critical of maximum plastic shrinkage cracking being about 0 . 5
本文研究了配制参数、主要原材料以及环境条件对新拌混凝土塑性收缩裂缝的影响,结果表明: 1 )单方混凝土水泥用量一定时,较低水灰比和较高水灰比对应的混凝土拌合物不易开裂,而中间某一临界水灰比对应的混凝土拌合物开裂较严重,这一临界水灰比为0 . 5 ;单方混凝土水用量或水泥浆量一定时,混凝土拌合物的塑性开裂趋势与上述情况相似,但临界水灰比分别为0 . 45 - 0 . 4和0 . 4 。
